Pronounce as per-TU-sis (US) or puh-TAH-sis (UK/AU). The primary stress is on the second syllable. IPAUs: /pərˈtʌsɪs/; IPAUK/AU: /pəˈtæsɪs/ or /pəˈtʌsɪs/. Begin with a light schwa on the first syllable, then a clear, stressed second syllable with 't' followed by a relaxed 'us' ending. For clarity, isolate: per-TUS-sis. Audio resources: consult medical pronunciation guides or Cambridge/Oxford dictionaries for audio.
Common errors include flattening the second syllable to /ˈpɜːrtəsɪs/ or misplacing stress as on the first syllable. Another frequent mispronunciation is turning the 't' into a harder or glottal stop and misarticulating the ending as /-ˈsɪz/ instead of /-sɪs/. Correction: emphasize the second syllable with /ˈtʌ/ or /ˈtæs/ using a clean /t/ and a full /ɪs/ ending. Listen to trusted dictionaries and repeat in phrases.
In US English, you’ll hear /pərˈtʌsɪs/ with a rhotic schwa initial and stress on the second syllable. UK/AU varieties tend to /pəˈtæsɪs/ or /pəˈtʌsɪs/ with nonrhotic or lightly rhotic R, and slightly more open vowels in the second syllable. The main differences are vowel quality and rhoticity; the second syllable remains stressed, while the first becomes a softer, unstressed schwa.
The difficulty lies in the two-syllable rhythm with a stressed second syllable, plus the cluster /t/ followed by /ɪ/ or /ɪs/ which can produce an unclear ending. Non-native speakers may insert extra vowels or misplace the stress. The word’s Latin-derived roots and medical usage may lead to slower, cautious enunciation. Practice with minimal pairs and connected speech to lock the stress and vowel quality.
Pertussis contains a straightforward consonant-vowel pattern with no silent letters; the tricky part is the second syllable’s vowel and the /t/ transition before /ɪ/ or /ɪs/. The consonant cluster is clear, but the vowel realization changes slightly by accent. Focus on the second syllable nucleus, keep the /t/ crisp, and end with a clear /s/ rather than a z-like sound. IPA cues help maintain accuracy.

Pertussis comes from the Latin pertussus, from pert- (intense, full of) and tussis (cough). The term was popularized in the 18th and 19th centuries as medical science formalized the disease historically known as the ‘whooping cough’. The root tussis appears in several Romance languages as a word for cough, while pert- aligns with intensifying prefixes in Latin. The earliest clear medical usage traces to European physicians describing a severe catarrhal illness with paroxysmal coughing. Over time, pertussis became the standard medical term in English, replacing vernacular descriptors of the disease and integrating into modern epidemiology and vaccinology discourse. The spelling and pronunciation stabilized in medical literature through the 20th century, with pronunciation variants influenced by English-speaking regions.
